LIQUID-MEASURING GAGE.

Specification of Letters Patent.

Application filed April 22, 1915. Serial No. 23,247.

To all whom it may concern Be it known that I, Josnrn C. Brown, asubject of the King of Sweden, residing at Cranston, in the county ofProvidence and State of Rhode Island, have invented certain new anduseful Improvements in Liquid- Measuring Gages; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable othersskilled in the art to which it appertains tomake and use the same.

This invention relates to liquid gages and more particularly to a devicefor indicating the depth of liquid in gasolene tanks of automobiles ormotor-boats.

The primary object of the invention is the provision of an indicatingdevice mounted in a cap which may be applied to the filling opening ofany tank so that the formation of additional openings through the wallsof the tank is rendered unnecessary and which is simple in constructionso that it may be applied at small expense.

With the above and other objects in view the invention resides incertain novel features of construction and combination and arrangementof parts as will be more fully described and claimed.-

In the accompanying drawings :Figure 1 represents a side elevation of aportion of a tank equipped with this improvement; Fig. 2 is alongitudinal vertical section thereof showing the gage in lockedoperative position; Fig. 8 is a detail sectional view of the cap withthe gage bar in lowered position; Fig. 4: is a plan view thereof.

In the embodiment illustrated a gasolene tank 1 is shown which may be ofany preferred or desired construction and which is 40 provided with anenlarged mouth or filling opening 2 internally threaded to receive theclosure carrying the indicator bar to be described.

The closure constituting this invention comprises a cup-shaped cap 3,the side walls of which are threaded as shown, at 4 to adapt it forthreaded engagement with the mouth 2. This cup is provided at its outeredge with alaterally extending ,fiange 5 which is adapted to projectbeyond its side walls and, when the parts are assembled, to rest on theouter edge of the mouth 2 as is shown clearly in Fig. 1. This cup-shapedcap has an upright reinforcing rib 6 extending diametrically thereacrossand provided at its center with an opening 7 extending through the capPatented Sept. 19,1916.

and rib, and which is here shown angular in cross section. A tubularmember 8 depends from the dower face of the cap 3 around the opening 7therein, and the cross sectional contour thereof is shown correspondingto that of the opening 7 both of which are shown angular and which aredesigned to receive and guide the vertical indicator bar 15 which isalso angular in cross section but they may be of any other shape. Therib 6 on its upper edge midway of its ends and around the opening 7therein is provided with a notch or seat 9 which is designed to receivetheupper end of the bar 15 when the bar isv in its extreme innerposition, said end having a cotter pin 10 or similar stop memberextending transversely thereacross to prevent it from being drawnthrough the opening 7 when it is so disposed. This cotter pin is housedin the seat 9 and is designed to be held therein when the gage is not inuse, by a locking bar 11 which is pivotally connected at one end to therib 6 at one side of the seat 9 therein, and is of a length sufficientto span said seat and extend some distance beyond the opposite sidethereof. This bar 11 is provided at its free end with an upturned handle12 for shifting the bar. laterally to cover or uncover the seat as maybe desired, or this bar may be fastened by any other means.

Projecting inwardly from opposite sides of the rib 6 on the side of theseat opposite that which carries the locking bar 11, are two lugs 13 and14: between which the free end of the bar 11 is designed to bepositioned and held thereby in looking engagement with the bar extendingover the seat 9 and over the end of the indicator bar 15 as is shown inFig. 4 and whereby said bar is locked in its retracted position to holdit out of the way when not in use.

A float 16 is secured to the lower or inner end of the bar 15 by anysuitable means and said float is here shown of less diameter than thediameter of the opening or mouth 2 to provide for its ready insertionand re-.

moval through said mouth.

As shown. the indicator bar 15 extends tl'irough the float 16 and saidfloat is held in engagement therewith by two cotter pins 17 and 18 whichextend transversely through the bar 15 at points above and below saidfloat although it is obvious that any other suitable means may beemployed for fastening the float to the bar.

Normally the parts will be held in the position shown in Fig. 2 with thelocking bar extending across the upper end of the indicator bar, whetherthe tank is full or empty, and whereby the float 16 will be heldsubmerged. If, however, it is. desired to ascertain the depth of theliquid in the tank, the bar 11 is disengaged from the lugs 13 and 14 andswung laterally from overthe seat 9 thereby liberating the indicator bar15 so that the float 16 will rise to the surface of the liquid and liftthe bar 15 to a height corresponding to the depth of the liquid in thetank, said bar 15 being providedwith graduations to indicate the depthof the liquid as will be obvious. Vhen the depth of the liquid has beenascertained the bar 15 is pushed down with its upper end disposed in theseat 9 and the locking bar 11 is swung over said end and held againstlateral movement by the lugs 13 and let.

I claim as my invention A measuring gage of the class describedcomprising an externally threaded cupshaped cap for attachment to thefilling opening of 'a tank, an-upri ht rib extending diametricallyacross the upper sideof said cap and having a notch in its upper edgemidway the ends thereof, said cap and said rib having a verticallyextending passage therethrough, a. locking bar pivoted to the upper sideof said rib and having its free end upturned, said bar being of alengthsuflicient to span said notch, a vertically slidable indicator barmounted in said passage and having a stop member at its upper endreceived'in said notch, the upper end of said indicator being disposedbeneath said locking bar when. the latter is inv its operative position,and a float at the lower end of said indicator bar.

.In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
